District sewers shall be established for the districts created to be prescribed by ordinance, and shall connect with public, or other district or joint district sewers or with a natural course of drainage, as each case may be, and may be constructed with the main branch or discharge pipe wholly within or beyond the boundary of the district as the council shall determine. The district may be subdivided, enlarged or changed by ordinance at any time previous to the construction of the sewer therein; and more than one district sewer may be laid in a sewer district if deemed necessary by the governing body of the municipality for sanitary or other purposes. The governing body shall cause sewers to be constructed in each district whenever a majority of the property holders shall petition therefor, or whenever the governing body shall deem the sewers necessary for sanitary or other purposes, and the sewer shall be of such dimensions and materials as may be prescribed by ordinance and may be changed, enlarged or extended, and shall have all the necessary laterals, inlets, catch basins, manholes and other appurtenances.
